neo4j - Spring Data Neo4j 4.0 の Neo4j TimeTree

Question

spring data neo4j 4.0.0 プロジェクトで timetree ライブラリを利用しようとしています。

このページhttps://github.com/graphaware/neo4j-timetreeで詳しく説明されているように、neo4j.properties ファイルを編集して、イベントの自動添付を有効にし、timetree 依存関係を gradle に追加し、プロパティ「creationDate」を設定しました。 Long データ型のイベントノード。すべてが正しいように見えますが、タイムツリーは作成されません。

これが私のneo4j.propertyファイルです：

# Runtime must be enabled like this
com.graphaware.runtime.enabled=true

# A Runtime module that takes care of attaching the events like this (TT is the ID of the module)
com.graphaware.module.TT.1=com.graphaware.module.timetree.module.TimeTreeModuleBootstrapper

# Nodes which represent events and should be attached automatically have to be defined
com.graphaware.module.TT.event=hasLabel('StructureVersionChange'),hasLabel('RuleVersionChange'),hasLabel('FilterVersionChange')

# Optionally, a property on the event nodes that represents the the time (long) at which the event took place must be specified (defaults to "timestamp")
com.graphaware.module.TT.timestamp=creationDate

# Optionally, a resolution can be specified (defaults to DAY)
com.graphaware.module.TT.resolution=SECOND

# Optionally, a time zone can be specified (defaults to UTC)
com.graphaware.module.TT.timezone=CEST

# Optionally, a relationship type with which the events will be attached to the tree can be specified (defaults to AT_TIME)
com.graphaware.module.TT.relationship=CREATED_ON

# autoAttach must be set to true
com.graphaware.module.TT.autoAttach=true

実際、これより前に、プロジェクトで Timetree の JAVA API バージョンを使用しようとしましたが、timetree コンストラクターのパラメーターの型である Node.js に本当に混乱しました。一方、春には、ノードにはクラスの型があります。

事前に感謝し、あなたの提案は本当に高く評価されます!

TimeTree の可能なラベルの定義には、InclusionPolicy ドキュメントで説明されているように、構文が少し異なりますhttps://github.com/graphaware/neo4j-framework/tree/master/common#inclusion-policies

構文は次のとおりです。

com.graphaware.module.TT.event=hasLabel('StructureVersionChange')||hasLabel('RuleVersionChange')||hasLabel('FilterVersionChange')

デバッグの目的で、これらの行をconf/custom-logback.xmlファイルに追加することができます:

<appender name="EXTENSIONLOG"  class="ch.qos.logback.core.FileAppender">
  <file>data/log/extensions.log</file>
  <encoder>
      <pattern>%date{yyyy-MM-dd HH:mm:ss.SSSZ} %-5level [%logger{15}]: %message%n</pattern>
  </encoder>
</appender>

<logger name="com.graphaware" level="debug">
  <appender-ref ref="EXTENSIONLOG"/>
</logger>

extensions.logファイルを見てください
